I caught my girl cheating on me, so I grabbed sancho and beat the living hell out of him, and finished by knocking him out by punching the spleen, sprinkling birdseed and honey all over him, dragging his naked body onto a crowded street before finishing off his punk arse with a nice set of panda eyes.

In the midst of a ferocious blow job, the male member can spontaneously wang to one side and out of alignment with the oral oriface. This is problematic since, through simple physical mechanisms, the most common destination of the wanging willy is the concavity of the blow job giver's eye socket. The result is almost universally a black eye. Panda Eyes are achieved when the owner of the wanging willy deliberately wangs towards the other eye socket in a quest for bilateral symmetry!
